I run development teams but keep my hands dirty, normally with a combination of these: Node, PHP, Javascript (React, Vue, D3, Three.js, WebGL, WebAudio, blah blah blah), AWS (the kitchen sink), C#, MySql, MsSql, PostgreSQL, NoSql (the usual suspects), Unity, Processing, Concrete5, Drupal, WordPress; but am happy to pick up anything. Right tool. right job (erm??)
